DataStreams: | sgp915rwpwindconC1.a1 |
Description: | DATA REPROCESSED and CORRECTED: In the moment datastreams (precipmom and wind mom) from the 915 RWP, the snr variable, is not set to missing value when the SNR is invalid but the other moments have valid values. At these points the SNR has a value of 32767. The ingest was updated and the data were reprocessed to fix the issue. The data were Archived in July 2016. Please retrieve the reprocessed data for use in your analysis. You may find these data using the ARM Discovery tool at the following link: http://www.archive.arm.gov/discovery/#v/results/s/finst::rwp/fsite::nsa/ffac::nsa.C1 http://www.archive.arm.gov/discovery/#v/results/s/finst::rwp/fsite::sgp/ffac::sgp.C1 ORIGINAL DQR CATEGORY: Yellow( Suspect) REPROCESSED and CORRECTED DATA ARCHIVED:2016-07 REPROCESS IDENTIFICATION NUMBER: RID 392 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- The SGP.C1 915RWP was operated in a non-standard mode during the Nocturnal Flux IOP (approximately the month of September). The profiler was placed into a constant high temporal and spatial resolution mode rather than alternating between modes as it does routinely. 30 min averages were produced (usually 60 min) at a 60 m gate resolution for both winds and RASS. Data were processed and archived, but the processing algorithm interpreted this data as 2 different power levels per hourly sample rather than 30 minute samples at the same power level. Data will be reprocessed. |

Description: | On Saturday and Sunday, December 26 and 27th a powerful winter storm (Goliath) brought sleet and freezing rain to much of Oklahoma with wind gusts of 45 MPH at times. The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use. |

Description: | A freezing rain event potentially affected some of the STAMP and MET tipping bucket rain gauges. The rain accumulation amounts generally agree (2 exceptions noted below) but the timing and rate of precipitation may disagree at times between the STAMP and MET. Instruments at E33 and E39 were found to differ more than the expected uncertainty and will be covered in additional DQRs if a problem is found. |
